Like with others seems risk management is one of the most lacking by everyone because even though they have a knowledge and skills but they get lack with the risk management is they didnt make it at all with the profit getting greedy with their trade instead taking profit they choose to be wait until where the market could bring it also with trading once you see lossing your money other makes fear and commit another greedy trades because they want to earn back their losses. I recommend always stick to the trading strategy that works on you still continuously learning to adopt.
